Le emissioni di gas serra sono aumentate fino ad un livello record, nonostante tutti gli sfozi intrapresi per il loro contenimento. È l'allarme lanciato domenica dal Gruppo intergovernativo di esperti sui mutamenti climatici (IPCC)
Fra il 2000 e il 2010 la crescita delle emissioni è avvenuta anche più rapidamente rispetto ai 3 precedenti decenni, rileva l'ultimo rapporto dell'IPCC.
Gli esperti sostengono che sarà comunque possibile - attraverso misure politiche e sviluppi tecnologici - limitare l'aumento della temperatura globale a 2 gradi rispetto ai livelli preindustriali.
Sarà tuttavia necessario tagliare le emissioni entro il 2050 in una misura compresa fra il 40 e il 70%, rispetto al 2010, per poi arrivare ad un valore vicino allo zero entro la fine del secolo.
